CONCRETE-BUILDING APPARATUS.

To all whom it may concern:

Be it known that I, RICHARD W. FULLER, a citizen of the United States,and a resident of Webster township, in the county of VVoodward and Stateof Oklahoma, have made certain new and useful Improvements in CombinedAdjustable Concrete-Building Apparatus, of which the following is aspecification.

My invention relates to improvements in adjustable molding devices forconcrete buildings, and it consists in the combina tions, constructionsand arrangements here in described and claimed.

An object of my invention is to provide an improved device over thatshown in myprior application, Serial Number 556,464, filed April 20,1910. These improvements consist mainly in the means for fastening thecorners of the mold members together, improvements in the shape of thecore blocks, the simplifying of the construction of the adjustablemolds, and other new features which will be set forth in thespecification.

My invention is illustrated in the accompanying drawing forming part ofthis application in which similar reference characters indicate likeparts in the several views, and in which Figure 1 is a perspective viewshowing the mold members in position for forming a portion of the wallincluding the corner, Fig. 2 is a transverse section through the moldand wall showing the core blocks and dividing plate in position, Fig. 3is a perspective view showing the collapsible chim ney mold, Fig. 4 is aplan view showing the folded position of the chimney mold, Fig. 5 is asection along the line 55 of Fig; 3, looking in the direction of thearrows, Fig. 6 is a section along the line 6-6 of Fig. 8, looking in thedirection of the arrows, Fig. 7 is a plan View of a portion of thecircular mold for making cylindrical structures, or curved walls, Fig. 8is a side view of a silo showing the use of the circular mold sections,Fig. 9 is a plan view of the apparatus for constructing the chimney andthe adjoining partition walls, Fig. 10 is a section along the line 101Oof Fig. 9, looking in Specification of Letters Patent.

Application filed September 15, 1911.

Patented May 28,1912. Serial No. 649,483.

In carrying out my invention I provide mold members for the walls, suchas those shown at 1 and 2 in Fig. 1. Each of these mold members isprovided with an upper and a lower outwardly extending flange, likethose shown at 1 and l while at intervals between the flanges arebraces, such as those shown at 1. The end braces are extended to formattaching means for the core supports 3, the latter being pivotallyconnected to the upright braces by means of the removable pins 4. Asshown in Fig. 2 the core supports 3 are provided with a series of holes3 each of which is adapted to receive the pivot pins 4, thus permittingthe adjustment of the molds toward or away from each other. These coresupports are reversible. In the figure I have shown them as beingprovided with three sockets or slots on the upper side and two on thelower, but it will be understood that any other number of sockets, suchas five on the upper side and four on the lower, might be used withoutdeparting from the spirit of the invention.

The inner surface of the mold member 2 is grooved to form blocks such asthose shown at 2 to give the appearance of concrete blocks when the wallis finished. At 2 I have shown a cut-away port-ion with a curved insertZZ above it. The cut-away portion is for the purpose of forming a window cap. This is given as an illustration of the means by which thewindow caps, window sills, and door sills are formed, the two lattervarying merely in the shape of the cut-away portion 2 Extending throughthe braces 1 and through the walls 1 and 2 of the mold, near the bottompart, are the tapering threaded crank bolts, such as those shown at 5for clamping the molds in position. These bolts, as clearly shown inFig. 2, are threaded at the ends to engage L-shaped plates 6, and areprovided with collars such as that shown at 5 to engage similar plateson the opposite mold member.

The means for joining the corners of the molds is different from that inmy prior application referred to. It will be noticed that the flanges 1and 1 are beveled from the end brace member 1 toward the wall 1, asclearly shown at 1 and 1 respectively. One of these mold members isformed with an extension 1 to which is secured a wedgeshaped block 1*,having a flange 1 arranged to enter a socket in the extension 1 of thecompanion wall member. A hook 7 is arranged to join these two wallmembers to-.

gether. The outer mold members have extensions, such as those shown at 2and 2", which are serrated on the inner sides so as to give the cornerblock a serrated finisli. Where 'a round corner is desired, a plate 8may be placed between the extensions 2 and 2 and the main wall 1, asshown in Fig. 1.

The dividing plates 9, which are used when it is desired to construct adouble wall, and the core blocks 10, which are used for making airspaces in the wall, are shown in Figs. 11 and 12, respectively. Thesedividing plates and core blocks are arranged on bars 9 and 10. The shapeof the dividing strips is shown in Fig. 13. It will be noticed thatthese strips are beveled at their sides. The core blocks 10 are taperedslightly from their upper to their lower ends, and are pointed to permittheir ready withdrawal or insertion. As will be seen from Fig. 15, thecore blocks are of a T-shape, and are spaced from each other, while inFig. 16 it will be apparent that the dividing plates are arranged closetogether. The suspension bars 9 and 10 are placed in the sockets in thecore support 3. Fig. 2 represents a double wall with a single air spacein each wall. A horizontal section of such a wall is shown in Fig. 18.

In Figs. 3 to 6 inclusive, I have shown the chimney core or moldmembers. This consists of an outer rectangular member having four walls11 of sheet metal pivotally connected together at their ends by theremovable pins 11*. The outer wall 1nembers 11 have upper outwardlyextending flanges 11 and lower outwardly extending flanges 11. Atintervals near the bot-tom of the walls, triangular flange members 11are struck inwardly from the metal in order to provide a support for theouter walls 11, as will be hereinafter described. The inner member ofthe chimney core consists of eight parts 12, hinged together in such amanner that the structure can be folded in the position shown in Fig. 1,alternate hinges being on opposite sides of the walls. Each of theseparts 12 has an outwardly turned upper flange 12, and an inwardly turnedflange 12? (see Figs. 6 and 10), and outwardly struck triangular flanges12.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

In beginning the foundation of the building, the parts are set up asillustrated in Fig. 1. The cement or concrete is placed between thewalls and is tamped down solidly. Before the concrete has set the crankbolts 5 are removedand the hook 7 is unfastened. Consider the wallportion at the right of Fig. 1. It may be swung inwardly when the crankbolts 5 are removed, this operation being permitted by the tongue andgroove connection with the adjacent wall member. The right hand moldmember may now be lifted out of the way by anysuitable hoisting means,such as that shown in my prior patent above mentioned. The other moldsection may be similarly moved. The foundation wall is now laid. Inbuilding the remainder of the wall the operation is as follows: If it isdesired to make a double wall, with an air space in each wall, the coreblocks are arranged on each side of the dividing plates in the mannershown in Fig. 2. If it is desired to build a single wall with three airspaces, a row of core blocks may be substituted for the middle dividingplate, and it is preferable that the core blocks be staggered, as shownin Fig. 17. It is obvious that any number of air spaces might beprovided or any number of separate walls by the use of the appropriatenumber of rows of core blocks or dividing plates. The core blocks ordividing plates are removed by lifting them vertically. The taperingform of the core blocks permits their withdrawal with ease. After anadditional section or wall has been built and the core blocks arelowered their pointed bottoms will facilitate the guiding of the coreblocks into place so as to make the air spaces register.

In Fig. 9 I have shown the means by which the chimney is made. In thisfigure, it will be seen that the four partition walls are made by thefour mold members 13, 14c, 15 and 16, the ends of these mold membersbeing beveled to fit the corners of the chimney, which is molded onecourse ahead of the partition walls, as shown in Fig. 10. After thefoundation block the chimney core is set up, as shown in Fig. 3. Aspacing plate 17 (see Fig. 10) is lowered into the interior of the moldmember 12 and rests on the in wardly turned flange 12 A top spacingmember or plate 18 is placed in the opening and rests on the flanges11". This prevents the collapsing of the inner mold member 12. Theconcrete is now filled in between the members 11 and 12, and when it isset the spacing members 18 and 17 are withdrawn, the inner member iscollapsed, as shown in Fig. 4 and withdrawn, one of the pins 11 is takenout of a corner of the outer mold member, and the outer member is openedup. hen building the subsequent layers of the chimney, the outer moldmember 11 is suspended on the foundation wall by means of the struck-inflanges 11' (see Fig. 5) while the inner mold member rests on thefoundation wall by means of the outwardly struck flanges 12 (see Fig.6). The partition walls are built similar to the outer walls, but inthis case it is desirable to have only a single air space, as shown bythe single socket in the core suspending member 3.

In Figs. 15 to 18 inclusive, I have shown the means for forming the doorand window openings where the building is designed to be entirelyfire-proof. Thus in Figs. 15 and 17, 19 designates the core for the dooropening. It will be seen that this core rests on a sill 20, which isconstructed precisely in. the same manner as the window cap de scribedin connection with Fig. 1. The door core may be taken apart when thecement is set hard enough to permit its removal, so as to leave a casingmade of concrete, as shown in Fig. 17. In Figs. 16 and 18, I have showna window core 21. This window core may be removed in the same mannerdescribed in connection with the door core, and when removed provides arecess 21 for blinds, grooves 21 for the Window sash and a recess 21 fora screen.

It will be obvious that my molding device may be used for buildingcylindrical structures such as silos or the like. In Fig. 7, I haveshown an arc-shaped section 22 of the inner and outer mold members forthe wall. These members overlap, as shown at 22, one having extensionsentering between the extensions on the other. In building a silo, suchas that shown at 23 in Fig. 8, the mold members are placed together andthe concrete is filled between. Starting from the ground, the moldmembers are inclined, so that when a portion of the wall hassufficiently set the mold members may be shifted and joined to the end,the operation proceeding in a spiral direction. Bet-ween the adjacentlayers a strengthening cable 24 is placed so that when the concretehardens the cable will form a spiral strengthening band to reinforce thewall. IVhen the top of the silo is reached, concrete can be filled in,thus tapering the wall OH to a level.

In Fig. 19 I have shown a portion of the rectangular walls 25 of abuilding which have been constructed by the use of the mold members suchas those shown in Fig. 1, the walls being provided with the windowopenings 25 and the door openings 25. At 26 is shown a portion of acircular wall which is being erected by the use of the curved mold forms22, such as those already described in connection with the making of thesilo. It will be apparent that these forms may not only be used forsilos, but for making curved walls of any description.

I11 Fig. 20 I have shown a plan view of a silo, such as that describedin connection with Fig. 8. In this figure the wall is shown at 23, thecurved mold members at 22 and the strengthening cable is wound in aspiral form and is disposed between the layers of concrete, so that whenthe concrete hardens the cable will reinforce the wall.
